Earlier today on Facebook, the team at Milviz uploaded a preview of the FMS220 in their upcoming ATR for Prepar3D. Shown is the INIT page and the programming of an initial flight plan.
Unfortunately, there is no further information regarding the ATR shared at this time. Earlier this year Milviz shared previews of the ATR’s overhead panel, they can be found here. A few weeks back we had a live interview with Colin Pearson and were shown product previews of not only the ATR, but many other soon-to-be-released products. You can check out the interview on Youtube.
